The same revision renamed group 3010 from Food & Staples Retailing to Consumer Staples Distribution & Retail, and group 2550 from Retailing to Consumer Discretionary Distribution & Retail. The renaming is what made the move possible: the test shifted from what kind of store it is to what is mostly on its shelves. The payment networks moved into Financial Services the same day — the two cards describe one restructuring.", "moved_in": [{"ticker": "TGT", "name": "Target", "from": "Consumer Discretionary", "to": "Consumer Staples"}, {"ticker": "DG", "name": "Dollar General", "from": "Consumer Discretionary", "to": "Consumer Staples"}, {"ticker": "DLTR", "name": "Dollar Tree", "from": "Consumer Discretionary", "to": "Consumer Staples"}], "context_cn": "读者要记住的一件事:这条边界是会动的,所以任何跨 2023-03-17 的板块长序列都带着一个口径接缝。我们不把两段拼接、也不回溯重算——XLP 与 XLY 的历史曲线画的是各自当时的口径,这张卡片就是那道接缝的说明。三家搬家公司合计约占 XLY 迁出前权重的个位数百分比,但它们把必需消费的零售一侧从「超市 + 会员店」扩成了「超市 + 会员店 + 折扣百货」。", "context_en": "The line moves, and that is the thing to carry away: any long sector series spanning 2023-03-17 contains a definitional seam. We neither splice the two regimes nor restate the history — the XLY and XLP curves show each period on the definition in force at the time, and this card is the note on the seam. The three names were a single-digit share of XLY's weight on the way out, but they widened the retail side of Staples from supermarkets and warehouse clubs to supermarkets, warehouse clubs and broadline discounters."}
